"My partner held up one teen, 15 years old, who kept fainting and managed to get her to safety," said one fan who contacted us.

"We actually feared for our lives… [I'm] not sure I will ever be the same again after this experience."

Another concertgoer, Emma Brooghan, said that was stuck in a queue for two hours before being trampled on.

"About 10 or 15 people in front of me fell forward and I leaned down to try to pick up one of the girls in front of me, and the crowd just completely pushed right forward, and I'd say about 10 people were on top of me," she said.

"There were so many people on top of my legs, but my arms were free, so they were trying to pull my arms to get me out from underneath the crowd."

Managing director of Festival Republic Melvin Benn has issued an apology this afternoon.
